2. Set Up the NMIS RPC Service

Create a service file at Then you will need the service file and install into /etc/systemd/system/nmis-rpc.service with the following content:

[Unit]
Description=NMIS RPC Service
After=network.target

[Service]
ExecStart=/usr/local/nmis9/bin/nmis-rpc-linux
WorkingDirectory=/usr/local/bin
Restart=always

[Install]
WantedBy=multi-user.target

reload Reload the systemd or whatever and start the service

...

daemon and start the service:

sudo systemctl daemon-reload
sudo systemctl start nmis-rpc.service

Enable the service to start on boot:

sudo systemctl enable nmis-rpc.service

3. Install NMIS 9.5.1 or Later

Install nmis9.5.1 or greater

httpwget https://dl-nmis.opmantek.com.s3.amazonaws.com/nmis9-9.5.1a.run
chmod +x nmis9-9.5.1a.run
sudo ./nmis9-9.5.1a.run

...

4. Configure NMIS to Use RPC

Edit the NMIS configuration file:

on its next poll it should use rpc over classic
